Los paneles de espuma de polfmero de cloruro de polivinilo (PVC), conocidos como paneles de Xuefu y paneles de Andi, contienen polfmero de cloruro de polivinilo como composicion qmmica principal. Durante la produccion, una mezcla de PVC, un agente espumante y similares se espuma a alta temperatura, la masa fundida es entonces extruida por una extrusora y transportada a un molde para su conformado y enfriamiento y los perfiles despues del conformado se cortan para obtener los paneles deseados. La formulacion existente de materiales que forman los paneles de espuma de PVC tiene ciertas desventajas. Por ejemplo: (1) el efecto espumante no es tan adecuado y homogeneo, por lo tanto, falla en lograr el efecto de silenciamiento debido al uso de un solo agente espumante; (2) las composiciones de los materiales suplementarios no son tan apropiadas, dando como resultado una resistencia, dureza y tenacidad insuficientes de los paneles, acortando asf aun mas la vida util de los paneles; (3) es probable que el PVC se descomponga en condiciones de luz y calor, por lo que las propiedades de los productos no son estables; (4) ya que es probable que la superficie de las piezas de trabajo se ralle, el aspecto no es satisfactorio. Esos factores tienen una gran influencia en la calidad de los paneles. Por lo tanto, es necesario desarrollar un nuevo material compuesto de PVC para mejorar la calidad de los productos relativos de manera eficaz.Polyvinyl chloride (PVC) polymer foam panels, known as Xuefu panels and Andi panels, contain polyvinyl chloride polymer as the main chemical composition. During production, a mixture of PVC, a foaming agent and the like is foamed at high temperature, the melt is then extruded by an extruder and transported to a mold for forming and cooling and the profiles after forming are cut to obtain desired panels. The existing formulation of materials that form PVC foam panels has certain disadvantages. For example: (1) the foaming effect is not as adequate and homogeneous, therefore, it fails to achieve the silencing effect due to the use of a single foaming agent; (2) the compositions of the supplementary materials are not as appropriate, resulting in insufficient strength, toughness and toughness of the panels, thus shortening even more the useful life of the panels; (3) PVC is likely to decompose under conditions of light and heat, so the properties of the products are not stable; (4) Since the surface of the work pieces is likely to be scratched, the appearance is not satisfactory. These factors have a great influence on the quality of the panels. Therefore, it is necessary to develop a new PVC composite material to improve the quality of relative products effectively.

partes en peso de estabilizante. Ademas, se puede anadir una pequena cantidad de agente abrillantador (generalmente menos de 1,5 partes en peso) y fibra vegetal (generalmente 3-5 partes en peso), si fuera necesario.parts by weight of stabilizer. In addition, a small amount of brightening agent (generally less than 1.5 parts by weight) and vegetable fiber (generally 3-5 parts by weight) can be added, if necessary.

Las caractensticas y funciones de estas composiciones se describen como sigue.The features and functions of these compositions are described as follows.

Como resina termoplastica principal, el PVC es una clase de polvo blanco de estructura amorfa (o, partfculas con 08 mm o inferior). Sin un punto de fusion definido, el PVC comienza a ablandarse a 80-85 °C, se vuelve muy elastico a 130 °C y comienza a volverse viscoso a 160-180 °C. Por lo tanto, el PVC puede moldearse facilmente por plastificacion mediante calentamiento.As the main thermoplastic resin, PVC is a kind of white powder of amorphous structure (or, particles with 08 mm or less). Without a defined melting point, PVC begins to soften at 80-85 ° C, becomes very elastic at 130 ° C and begins to become viscous at 160-180 ° C. Therefore, PVC can be easily molded by plasticizing by heating.

Como materia prima qmmica comun, el carbonato de calcio ligero se prepara qmmicamente. El volumen de sedimentacion del carbonato de calcio ligero, es decir, 2,4-2,8 ml/g, es mucho mayor que el del carbonato de calcio pesado (1,1-1,9 ml/g) preparado mecanicamente. En el material compuesto de PVC de acuerdo con las realizaciones de la presente invencion, el carbonato de calcio ligero sirve como carga, y asf la dureza y la estabilidad del material pueden mejorarse de manera eficaz.As a common chemical raw material, light calcium carbonate is prepared chemically. The sedimentation volume of light calcium carbonate, ie 2.4-2.8 ml / g, is much greater than that of mechanically prepared heavy calcium carbonate (1.1-1.9 ml / g). In the PVC composite material in accordance with the embodiments of the present invention, light calcium carbonate serves as a filler, and thus the hardness and stability of the material can be effectively improved.

La funcion del agente espumante compuesto es facilitar la formacion de burbujas durante el calentamiento de las materias primas, para formar asf un producto acabado poroso, para finalmente reducir el ruido/sonido. El agente espumante compuesto en esta realizacion se puede seleccionar entre algunos productos existentes en el mercado, o puede estar formado de un agente espumante inorganico y un agente espumante organico. En un agente espumante compuesto espedfico, la proporcion del agente espumante inorganico (por ejemplo, bicarbonato de calcio, bicarbonato de magnesio, bicarbonato de sodio o similar) al agente espumante organico (por ejemplo, compuestos azoicos, compuestos de sulfonil hidrazina, nitrocompuestos o similar) es de 1:2 a 1:1. No de acuerdo con la presente invencion, el agente espumante compuesto puede incluir 0,6 ± 0,1 partes en peso de agente espumante organico azodicarbonamida (AC) como activadory 0,8 ± 0,1 partes en peso de bicarbonato sodico como agente espumante inorganico endotermico. En este caso, por un lado, se mejora la descomposicion subita de la AC y, por otro lado, es mas facil preparar un agente espumante deseado. El uso de un agente espumante compuesto mejorado de este tipo ayuda a aumentar la eficacia de la formacion de espuma y a asegurar que la espuma sea mas delicada y uniforme.The function of the compound foaming agent is to facilitate the formation of bubbles during the heating of the raw materials, so as to form a porous finished product, to finally reduce the noise / sound. The foaming agent composed in this embodiment can be selected from some products existing in the market, or it can be formed from an inorganic foaming agent and an organic foaming agent. In a specific compound foaming agent, the proportion of the inorganic foaming agent (for example, calcium bicarbonate, magnesium bicarbonate or sodium bicarbonate or the like) to the organic foaming agent (for example, azo compounds, sulfonyl hydrazine compounds, nitro compounds or the like) ) is 1: 2 to 1: 1. Not in accordance with the present invention, the compound foaming agent may include 0.6 ± 0.1 parts by weight of organic foaming agent azodicarbonamide (AC) as activator and 0.8 ± 0.1 parts by weight of sodium bicarbonate as foaming agent inorganic endothermic. In this case, on the one hand, the sudden decomposition of CA is improved and, on the other hand, it is easier to prepare a desired foaming agent. The use of an improved composite foaming agent of this type helps to increase the effectiveness of foam formation and to ensure that the foam is more delicate and uniform.

El regulador de espuma, como adyuvante de procesamiento de acrilato, es resina elastica. La funcion principal del regulador de espuma en los materiales de la presente invencion es facilitar la plastificacion de PVC, mejorar la resistencia de la masa fundida de PVC y evitar que las espumas se fusionen o se rompan y asegurar que la masa fundida tenga buena fluidez y mejore el brillo superficial del producto. En las realizaciones de la presente invencion, el regulador de espuma puede ser un regulador de espuma de la serie 530 (ZD530, LS530, BZ530, PA530, etc., que se refiere espedficamente a las introducciones de productos de JINHASS y otras empresas). El regulador de espuma es capaz de aumentar la presion y el par de torsion de la masa fundida de PVC para asf aumentar eficazmente la cohesion y la homogeneidad de la masa fundida de PVC y hacer los productos de PVC resultantes mas compactos.The foam regulator, as an acrylate processing aid, is elastic resin. The main function of the foam regulator in the materials of the present invention is to facilitate PVC plasticization, improve the strength of the PVC melt and prevent the foams from melting or breaking and ensuring that the melt has good fluidity and improve the surface brightness of the product. In the embodiments of the present invention, the foam regulator may be a 530 series foam regulator (ZD530, LS530, BZ530, PA530, etc., which specifically refers to the product introductions of JINHASS and other companies). The foam regulator is capable of increasing the pressure and torque of the PVC melt so as to effectively increase the cohesion and homogeneity of the PVC melt and make the resulting PVC products more compact.

El endurecedor es una sustancia utilizada para mejorar la tenacidad de la capa de material compuesto. Como adyuvante del proceso de plastificacion, la funcion principal del endurecedor es realzar la dureza y la resistencia de choque del producto. En esta realizacion, el endurecedor puede ser polietileno clorado (CPE) o de otro modo poliacrilatos (ACR).The hardener is a substance used to improve the toughness of the composite layer. As an adjuvant to the plasticizing process, the main function of the hardener is to enhance the hardness and shock resistance of the product. In this embodiment, the hardener can be chlorinated polyethylene (CPE) or otherwise polyacrylates (ACR).

La funcion principal del lubricante, como lubricante interno, es lubricar la superficie de contacto del material compuesto para hacer que tenga ademas una mejor fluidez, para evitar rallar las piezas de trabajo. El lubricante puede estar formado de acido estearico y cera de polietileno (PE), en el que los dos componentes se pueden preparar en una proporcion de aproximadamente la misma cantidad (0,8-1:0,8-1). El lubricante tambien puede acelerar la fusion del PVC, mejorar la resistencia y homogeneidad de la masa fundida, reducir la fractura y la exudacion de la masa fundida y no tener efectos adversos obvios sobre la propiedad mecanica del PVC.The main function of the lubricant, as an internal lubricant, is to lubricate the contact surface of the composite material to make it also have a better fluidity, to avoid scratching the work pieces. The lubricant can be formed of stearic acid and polyethylene wax (PE), in which the two components can be prepared in a proportion of approximately the same amount (0.8-1: 0.8-1). The lubricant can also accelerate the fusion of PVC, improve the strength and homogeneity of the melt, reduce the fracture and exudation of the melt and have no obvious adverse effects on the mechanical property of PVC.

El estabilizante se utiliza principalmente para ralentizar la reaccion de la sustancia, manteniendo el equilibrio qrnmico, reduciendo la tension superficial y evitando la fotolisis y la termolisis, la oxigenolisis o similares. En la presente invencion, la funcion principal del estabilizante es evitar la descomposicion de PVC, para asf asegurar la calidad del producto. En las realizaciones de la presente invencion, el estabilizante puede ser un estabilizante de jabon metalico. Espedficamente, el estabilizante se puede preparar a partir de estearato de calcio y estearato de zinc en una proporcion de aproximadamente la misma cantidad (0,8-1:0,8-1).The stabilizer is mainly used to slow down the reaction of the substance, maintaining chemical balance, reducing surface tension and avoiding photolysis and thermolysis, oxygenolysis or the like. In the present invention, the main function of the stabilizer is to prevent the decomposition of PVC, in order to ensure the quality of the product. In the embodiments of the present invention, the stabilizer may be a metal soap stabilizer. Specifically, the stabilizer can be prepared from calcium stearate and zinc stearate in a proportion of approximately the same amount (0.8-1: 0.8-1).

El agente abrillantador, tambien denominado agente abrillantador optico o agente abrillantador fluorescente, es una materia prima opcional. La funcion principal del agente abrillantador es hacer que el producto tenga el mejor aspecto. En esta realizacion, el agente abrillantador puede ser oxido de titanio, cuyo componente principal es TiO2 y que puede mejorar las propiedades del producto y puede reducir el coste del uso de los materiales en comparacion con otros agentes abrillantadores.The brightening agent, also called the optical brightening agent or fluorescent brightening agent, is an optional raw material. The main function of the brightening agent is to make the product look the best. In this embodiment, the brightening agent can be titanium oxide, whose main component is TiO2 and which can improve the properties of the product and can reduce the cost of using the materials compared to other brightening agents.

Se pueden anadir otros agentes adyuvantes, es decir, 3-5 partes de materiales suplementarios de fibra vegetal tales como polvo de paja, harina de madera, harina de bambu, o una mezcla de los mismos. Por una parte, los agentes adyuvantes pueden potenciar el efecto espumante y mejorar la densidad, resiliencia y tenacidad del producto, y por otra parte, los agentes adyuvantes contribuyen a la reduccion del coste integral de los materiales.Other adjuvant agents can be added, that is, 3-5 parts of plant fiber supplementary materials such as straw powder, wood flour, bamboo flour, or a mixture thereof. On the one hand, the adjuvant agents can enhance the foaming effect and improve the density, resilience and toughness of the product, and on the other hand, the adjuvant agents contribute to the reduction of the integral cost of the materials.
